Why together?
The Bible we Christians revere (this writer is Christian) was written almost exclusively by Jews although some religious scholars say “exclusively” written by Jews. Luke is the disciple some scholars question as to Jew or Gentile.
The Jewish people did not kill Jesus, the first “Christians” were Jewish. Their arrogant elders feared that the following Jesus was developing, would usurp their power and authority. These elders had Pontius Pilate do their dirty work. Think about it, we, Jews and Christians are stronger together.
